DEVICE

SPECIFICATION

S2046/S2050

GIGABIT ETHERNET CHIPSET

BiCMOS PECL CLOCK GEN RATOR

GENERAL DESCRIPTION

FEATURES

• Functionally compliant with the 802.3z specification

• S2046 transmitter incorporates phase-locked

loop (PLL) providing clock synthesis from low-

speed reference

• S2050 receiver PLL configured for clock and

data recovery

• 1250 Mbps (Gigabit Ethernet) operation

• 10- or 20-bit parallel TTL compatible interface

• +3.3/+5V power supply

• Low-jitter serial PECL compatible interface

• Lock detect

• Local loopback

• Compact 52 PQFP package

• Gigabit Ethernet framing performed by receiver

• Continuous downstream clocking from receiver

• TTL compatible outputs possible with +5V I/O

power supply

The S2046 and S2050 transmitter and receiver pair

are designed to perform high-speed serial data trans-

mission over fiber optic or coaxial cable interfaces

conforming to the requirements of the proposed 802.3z

specification. The chipset is Gigabit Ethernet compli-

ant and supports 1250 Mbps with an associated 10

or 20-bit data word.

The chipset performs parallel-to-serial and serial-to-

parallel conversion and framing for block-encoded

data. The S2046 on-chip PLL synthesizes the high-

speed clock from a low-speed reference. The S2050

on-chip PLL synchronizes directly to incoming digital

signals, to receive the data stream. The transmitter

and receiver each support differential PECL-compat-

ible I/O for fiber optic component interfaces, to

minimize crosstalk and maximize data integrity. Local

loopback allows for system diagnostics. The I/O sec-

tion can operate from either a +3.3V or a +5V power

supply. (See Ordering Information.)

APPLICATIONS

High-speed data communications

• Ethernet backbone connections

• Mainframe

Figure 1 shows a typical network configuration incor-

porating the chipset.

• Workstation

• Frame buffer

• Switched networks

• Data broadcast environments

• Proprietary extended backplanes
